Abstract
Description
- The present invention relates generally to the field of mobile communication devices such as mobile telephones and palmtop computers, personal digital assistants (PDA's), and the like providing telephony features, and more particularly to a mobile communication device capable of transmitting media content such as streaming audio data downloaded from the Internet, or the like, received via a wireless communication network to a receiver assembly in proximity to the mobile communication device.
- Mobile telephones, palmtop computers, personal digital assistants (PDA's), and the like, comprise a class of portable electronic devices whose size enables them to be held in one hand while being operated with the other. Often, such devices are connected to a wireless bearer service capable of providing access to a source of media content such as the Internet, allowing the user of the device to receive media content which may be stored in the device's memory, the memory of a computer system, or transmitted to others via the communication network.
- The capability of such devices for reproducing media content, however, is typically limited by their portability. For instance, the selection of speakers which may be included with a mobile telephone is limited by the size of the mobile telephone. These limitations may restrict the reproduction quality of the media content available to the user via the mobile telephone. For example, a typical speaker included with a mobile telephone is generally not suitable for reproducing high fidelity sound required for playback of media containing music. Oftentimes the user of a mobile telephone is located in the proximity of an audio or video reproduction system which is capable of such high fidelity presentation. For example, the user may be in an automobile or like vehicle equipped with an AM/FM radio tuner, satellite radio tuner, or the like. In such instances, it would be advantageous to provide media content received via the mobile telephone to a receiver assembly in proximity to the mobile telephone for reproduction as sound and/or video.
- Accordingly, the present invention is directed to a mobile communication device capable of transmitting media content received via a wireless communication network to a receiver assembly in proximity to the mobile communication device. The mobile communication device configures the media content for reproduction as sound and/or video prior to being transmitted to a receiver assembly for playback.
- In exemplary embodiments, the mobile communication device includes components for providing wireless communication of voice and/or data information via a wireless communication network. For instance, the mobile communication device may comprise a cellular telephone, a satellite telephone, a PDA, a palm top computer, a portable gaming device, or other device (e.g., an FM stereo receiver, a satellite stereo receiver or an MP3 player device) equipped with telephony features and sized to be held with a user's hand. The mobile communication device includes a transceiver assembly for communicating information with a wireless communication network, such as a General Packet Radio Service (GPRS) bearer service, an Enhanced Data for GSM Evolution (EDGE) bearer service, a Universal Mobile Telecommunications System (UMTS) bearer service, a Code Division Multiple Access (CDMA) bearer service, a Personal Communications Service (PCS) bearer service, a Time Division Multiple Access (TDMA) bearer service, a Global System for Mobile Communication Circuit Switched Data (GSM (CSD)) bearer service, a Wireless Local Area Network 802.11x (WLAN(802.11x)) bearer service, or the like. In embodiments, the wireless communication network provides access to a source of media content, such as the Internet.
- The mobile communication device may further include a transmitter assembly for transmitting media content received via the wireless communication network to the receiver assembly. Media content for transmittal via the transmitter assembly may include streaming audio data downloaded from the Internet via the wireless communication network, or the like. The transmitter assembly may be coupled with a software module for configuring the media content for reproduction as sound and/or video. For example, streaming audio data downloaded from the Internet may be configured via frequency modulation (FM) for radio frequency (RF) transmission, and the transmitter assembly may include an FM RF transmitter. The receiver assembly may be an FM radio tuner, or the like, for reproducing the RF transmission as sound.
- In specific embodiments, the memory of the mobile communication device is capable of storing at least a portion of the media content for transmittal to the receiver assembly. For instance, the mobile communication device may be capable of storing an MP3 file, an MPEG-4 file, a portion of streaming audio/video, and the like. The memory may be configured as a cache for providing continuous transmittal of a streamed audio/video program. For example, when packets of streaming audio data are received via the wireless communication network, portions of the audio data may be stored in the memory and utilized with a timed delay, such that a stored portion of the audio data is broadcast by the transmitter assembly while another portion is being received via the wireless communication network.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not necessarily restrictive of the invention as claimed. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention and together with the general description, serve to explain the principles of the invention.
